Final answer:
Amniotic fluid cushions the fetus, serves as the fluid for the fetus, maintains internal temperature, and protects from heat loss.
Step-by-step explanation:
Amniotic fluid serves multiple functions during pregnancy. It cushions the fetus from abdominal trauma, allowing it to be protected from external blows.
The fluid also serves as a medium for the fetus to move and develop in. Additionally, amniotic fluid helps maintain the internal temperature of the fetus and protects it from heat loss.
